The Radial Workhorse Powerhouse 500-Series Rack is a 10 space 500-Series power-rack designed to accommodate both older and newer modules and provide the studio with maximum density in a standard 19″ rack frame.
The design begins with heavy 14-gauge steel construction and durable powder coat finish for maximum shielding against noise and greater durability when subjected to road use. An 'easy glide' slider tray makes it painless to align the PCB connector to the 15 pin card edge receptacle when swapping modules. Once connected, the rear panel sports a standard array of XLRs to connect to and from the workstation or mixer. This is augmented with a series of ¼" TRS connectors that enable cross-patching and open the door to the excitement of parallel signal processing. Instead of having to hard patch modules together using a cable, the Powerhouse incorporates an innovative feed switch that instantly connects the signal to the adjacent module. This makes building signal chains quick and eliminates the need for extra cables. And unlike older racks that require soldering when modules are used in stereo, the Powerhouse is equipped with a stereo link function that takes care of the task with a simple slide of a switch. Unlike older racks that are limited to an average of 130 milliamps per slot, the Powerhouse boasts a 1600 milliamp power supply that lets you share the power as needed. This means it can deliver 300 milliamps to your two tube preamps and still have over 1000 milliamps left in the pool! And just like all Workhorse racks, the Powerhouse is equipped with extra safety features to ensure safe use when mixing and matching various brands.

Excellent 500 Series Option
Sep 15th 2025Upgraded to the Radial Workhorse from a Lindell Audio Power 510 (not the Mk II) as I was experiencing some issues with noise on a couple of the slots. I figured this would be a good time to try something new. The Radial Workhorse has been tremendous as far as being a reliable, extremely rugged and low-noise 500 series rack. Those same modules when loaded into the Workhorse have been dead quiet. I love the features of being able to link or feed audio from one 500 series slot to the adjacent slot. It would be nice on a future revision to see these switches placed on the front of the unit and it would also be great if there was a way to feed audio bi-directionally as opposed to just going from one unit to the next one to the right (when facing the rack). Although this can be solved with some careful planning when placing modules. Overall I love the unit and as a bonus it comes with a pack of thumbscrews AND flat heads should you prefer one over the other!
